RESUMO
BACKGROUND AND AIM OF THE STUDY: To report early clinical outcomes of the frozen elephant trunk (FET) technique for the treatment of complex aortic diseases after transition from conventional elephant trunk. METHODS: A single-center, retrospective study of patients who underwent hybrid aortic arch and FET repair for aortic arch and/or proximal descending aortic aneurysms, acute and chronic Stanford type A aortic dissection with arch and/or proximal descending involvement, Stanford type B acute and chronic aortic dissections with retrograde aortic arch involvement. RESULTS: Between December 2017 and May 2020, 70 consecutive patients (62.7 ± 10.6 years, 59 male) were treated: 41 (58.6%) for emergent conditions and 29 (41.4%) for elective. Technical success was 100%. In-hospital mortality was 14.2% (n = 12, 17.1% emergent vs. 10.3% elective, P = NS); 2 (2.9%) major strokes; 1 (1.4%) spinal cord injury. Mean follow-up was 12.5 months (interquartile range, 3.7-22.3). Overall survival at 3, 6, 12, and 24 months was 90% (95% confidence interval [CI], 83.2-97.3), 85.6% (95% CI, 77.7-94.3), 79.1% (95% CI, 69.9-89.5), 75.6% (95% CI, 65.8-86.9) and 73.5% (95% CI, 63.3-85.3). There were no aortic re-interventions and no distal stent graft-induced new entry (dSINE); 5 patients with residual type B dissection underwent TEVAR completion. CONCLUSIONS: In a real-world setting, FET with Thoraflex Hybrid demonstrated feasibility and good clinical outcomes, even in emergent setting. Our implant technique optimize cerebral perfusion reporting good results in terms of neurological complications. Techniques to perfect the procedure and to reduce remaining risks, and consensus on considerations such as standardized cerebral protection need to be reported.

Short-term mechanical circulatory support (MCS) devices are designed to provide hemodynamic support for a wide range of clinical conditions such as high-risk cardiac surgery or interventional procedures, post-cardiotomy cardiogenic shock, acute decompensated heart failure. Electrical storm (defined as three or more sustained episodes of ventricular fibrillation-VF- in a 24-h period) is a rare but critical complication following revascularization in patients with ischemic heart disease and it is associated with a very high mortality (80-90%) both during the incident alone and during further observation. Here we report the case of a 38-year-old patient affected by coronary artery disease with moderate to severe left ventricular systolic dysfunction (EF 30-35%) who underwent emergency coronary artery bypass grafting (CABG) complicated by electrical storm and severe haemodynamic instability, successfully managed with a novel approach of biventricular mechanical circulatory support with extracorporeal life support (ECLS) in first instance, subsequently switched to Impella CP and ProtekDuo.
